What Charleston Allergy and Asthma does

Charleston Allergy and Asthma, operating legally as Allergy and Asthma Consultants, LLP, is a private sub-specialty medical practice headquartered in Mt. Pleasant, South Carolina, founded around 1993. The practice diagnoses and treats allergic rhinitis, asthma, food allergies, drug allergies, insect allergies, skin allergies, immune deficiencies, sinusitis, and anaphylaxis for patients ranging from newborns to seniors across three Lowcountry clinic locations: Mount Pleasant, Summerville, and West Ashley. Care is delivered by seven physicians, all board-certified in allergy, asthma and immunology and dual-boarded for pediatric and adult populations, supported by standard clinical diagnostic and treatment modalities including skin prick testing, intradermal testing, patch testing, pulmonary function testing, subcutaneous immunotherapy (allergy shots), sublingual immunotherapy tablets, and food oral immunotherapy. The practice operates the area's certified pollen counting station, publishing daily pollen levels Monday through Friday, and runs an active clinical research department that has completed more than 300 investigative drug studies over the past 20 years.

The practice's commercial model is primarily fee-for-service medicine billed through most major insurance plans with patient responsibility (copays and deductibles) collected at time of service, supplemented by self-pay options. A secondary revenue stream comes from sponsor-funded clinical research, where participants may receive study medication at no cost or compensation. New and established patients can be seen in person at any of the three clinics or remotely via Doxy.me telehealth, with 24/7 self-service scheduling, prescription refills, bill payment, and lab-result access through a Medfusion patient portal and Phreesia intake system. The practice joined Allergy Partners, the largest U.S. allergy practice network, in 2023, aligning it with a national platform for research collaboration and physician recruiting while remaining physician-led at the local level.

Charleston Allergy and Asthma competes on depth of sub-specialty credentials, brand reputation built over 30+ years (including Best Doctors in America recognition for all physicians and more local consumer awards than any other area allergy practice), and convenience of multi-location coverage. Its marketing mix is content- and reputation-led, with an active blog, daily pollen reports, patient testimonials, social media, and local broadcast media coverage. Distribution is direct-to-consumer through clinics, telehealth, and the patient portal, with referral flows from other physicians reinforcing new-patient acquisition in a single tightly defined geographic market.
